Ultrafast electron–hole relaxation dynamics in CdS nanocrystals

Autor: Luca Moretti, Margherita Maiuri, Giulio Cerullo, Mahima Makkar, Ranjani Viswanatha

Publikováno v: Journal of Physics: Materials. 4:034005

Surface traps significantly influence the charge carrier dynamics within semiconductor nanocrystals, introducing non-radiative exciton recombination channels which are detrimental for their applications. Understanding the nature of these trap states
